December 21, 2012 -

The paved streets of New York city, Chicago, St. Louis, and other cities around the world were empty of pedestrians and traffic. No one travelled along these roads; the inhabitants of Earth having taken up the precaution of living in temporary underground bomb shelters. The same was true of the inhabitants of South Park Colorado.

The only person not given to the mass panic induced by ancient Mayan calendars was Stan Marsh. He was seated in the town gymnasium beside Kyle Broflovski, who, though being skeptical was also feeling the effects of the hysteria. The redhead looked calm but his hazel eyes were glued to the miniature television set Stan's dad had gotten hold of, and the news reporters.

At least he takes this better than Fatass, Stan thought.

Eric Cartman was sobbing and trembling like a glutinous blob of rotting Jell-O. Every now and then he would let out the annoyingly high pitched wail, "I don' wanna fucking diiiiiiiiiiieeee!"

Stan had tried to slap sense into the fat blubbering idiot, but Cartman continued to be a loud nuisance. "We're all gonna ! Kahl planned it all! !" Stan gripped the bridge of his nose and ground his teeth together. Not only was Cartman showing he had the backbone of a jellyfish, but had already added Kyle into the equation of the "Great Disaster of 2012."

"Shut the fuck up, Fatass!" Kyle and Stan both snapped at the same time. "We. Are. Not. Going. To. Fucking. Die!"

"Not going to die?!" someone repeated shrilly. It was Butter's mother. Though practically everyone else was wearing wild, feral expressions of animals knowing they were trapped, cornered, and ready to face a painful end, she was more so; her fingernails had been chewed until blood seeped from the fingertips, and occasionally her husband would violently shake her whenever she slipped into panic attacks. "We're all going to die!"

Her words were like a cue for Randy Marsh.

"We're all gonna die!" he cried out, making a show of waving his arms dramatically in the air. Stan hunched further to the ground. He wished he was completely invisible – his dad was making a complete fool of himself again and Stan would rather be somewhere else than around him.

"If we survive we'll end up as cannibals!" someone else said, and Stan recognized the voice of Mr. Garrison.

"Gyah! Cannibals?!" Tweak exclaimed. The blond-haired boy was twitching more spasmodically than usual and had fainted several times in the last half hour. Evidently the horror of their callous teacher's words had woke him up. Great.

"Don't worry, Tweak," his father said in a warm, comforting voice. "We'll probably eat you first so you won't have to suffer the horrible effects of fall-out."

How that was supposed to make him better, Stan had no idea. Tweak didn't seem very reassured by it; a squawk of horror escaped the boy's lips and he promptly fainted.

That did it. Stan had had enough of the stupidity of most of South Park inhabitants and stood to his short, stubby legs. "We're not going to die!"

But as soon as Stan said it, the earth rumbled and shook beneath his feet. On cue, the inhabitants of South Park ran around in panicked circles. Someone was repeating, "We're gonna die, we're gonna die," like a mantra. Kenny convulsed on the ground, clutching his chest, and then died.

"Oh my God! They killed Kenny!" Stan exclaimed out of habit.

"You bastards!" Kyle continued, also out of habit.

Stan wondered that, if everyone died, would everyone simply reappear like Kenny? Would everyone have another chance?

Then, all at once, something completely surreal and dreamlike happened. The air around Stan rippled like waves of the ocean, and then, mouth wide open in shock, he saw a stream of what looked like a fire burst from nowhere. He looked over at Kyle to see what his friends reaction was, but Kyle wasn't paying any attention. No one else was, for that matter. The only one who could see the bizarre fire was Stan.

The fire formed the head of a fox and then everything became stretched like taffy, intermixed, and then the world turned pitch black.

As the world literally fell apart around Stan, he felt he could hear the deep voice of someone talking angrily in Japanese:

"Who the hell are you?!"

Does he mean me? Stan lazily wondered, and then lost consciousness.

Five minutes earlier in another dimension,

Pain. Uzumaki Naruto clutched his side in agony, feeling warm blood seep from the wound. His teammate, Sakura, lay limp on her stomach in the dirt, bloody steel spikes protruding from her back. Kakashi wasn't dead, yet, but with the amount of blood he was using, he would be.

"Do you see it, Naruto-kun? Do you see my way of reasoning?" the horribly calm voice of Uchiha Madara said. "Free will causes only pain, suffering, and war. When my plans come to fruition there will be no more free will; I will control everything and everyone. Wouldn't you like Sakura-chan to live, Naruto?"

Naruto coughed up blood. Why the hell wasn't the Kyuubi responding? He sure as hell had been active during Pain's invasion!

Everywhere around him, he could smell the stench of blood and hear the death gurgles of the fatally wounded. He knew, unlike the outcome of Pain's invasion, that there would be no merciful restoration of life from a repentant Uchiha Madara. Everyone who was dead were going to stay dead. In one long hour, most of Naruto's friends were either dead or critically injured.

"Na…ru…" Kakashi gasped, and then died.

For the first time in his life, he truly wanted to allow the Kyuubi to take control, to give into the black, boiling rage churning inside the recesses of his mind. Everything was death and decay. He wanted Madara to feel torturous agony before death, to savor the renegade Uchiha's death throes under the burning red chakra of a malevolent Kyuubi. A small part of Naruto felt fear over the graphic mental images and watched the Uzumaki Naruto of yesterday slip away. The ninja who never gives up was giving up? The shinobi who never wanted to rely on the Kyuubi's chakra was now craving it?

"The Kyuubi won't save you this time, of course. I can easily control him," Madara continued matter-of-factly.

Naruto lurched to his feet, swayed, and then darted clumsily toward the monster. The man had killed Sakura-chan, Kazekage Gaara, Sai, and Kakashi-sensei! This was too much. Eyes burning with tears of rage, Naruto formed a Rasengan and aimed it at Madara.

Madara's form flickered so that it looked like Naruto passed through him.

Madara's hands moved in a blur as he made signs. Naruto felt no fear; he had seen innocent villagers turn on each other for no apparent reason and had witnessed Sakura and Kakashi battle each other to the death. Anything more would be meaningless. If he died it would only be an end to the continual cycle of grief and madness that began with Sasuke's betrayal of Konoha.

"Cycle of the Other Worlds no Jutsu!" The black pinpoints of Uchiha Madara's sharingan merged with his pupil and then, his entire eye became pitch black. Naruto found he couldn't look away. A paralysis jutsu? "I've decided to make you see how different the world would be under my leadership," he said, "You should be glad I'm letting you see this!"

Madara's mask turned into a spinning vortex, the black hole for his one good eye becoming larger than Naruto's head.

Two things happened as Naruto was sucked into Madara's eye (or into the gateway of the other world). One thing that happened was the Kyuubi chakra was suddenly seeping from his skin as the seal suddenly disappeared. The other thing that happened was the Kyuubi suddenly took over Naruto's body completely, and ripped out Madara's heart.

The next thing Naruto knew, he was in complete pitch blackness of neither here, there, or anywhere. Then, he was suddenly overwrought in excruciating agony as the Kyuubi ripped out of his body. The pain was intense. And then silence and the knowledge Naruto was, for the first time since the day the Kyuubi was sealed into him, completely and utterly alone…

What the hell is happening?!

The darkness convulsed and then Naruto knew nothing more.
